While early explorers either sailed the seas or trekked overland, 20th century explorer Jacques Cousteau's territory of discovery was underwater. This exciting new book details the expeditions of this submarining adventurer and inventor. Before Cousteau, underwater exploration was limited and dangerous. Cousteau perfected the aqualung in 1943 which made it possible for divers to stay underwater for several hours. His many undersea adventures were documented in books, films, and television shows which brought the world under the water to life for millions of people. Topics include
• Cousteau's early career in the French navy
• undersea exploration before Cousteau
• ocean conservation and Cousteau's work with whales and dolphins
• the research ships and inventions
• Cousteau's work on an underwater living research program
